# Configure Discrete Output Details

The Output Details dialog is used to configure individual output line parameters from within the Discrete I/O Settings dialog.

1. From the Tools menu, click Discrete I/O Settings.

2. From the Discrete I/O Settings dialog, choose an output line to configure and click Details.

   Note: No output details are configurable for High, Low, Busy and Online Signal Types.

   The appearance of the Output Details dialog varies, depending on the output line Signal Type:

   Signal Type | Output Details Dialog
   Programmed (Default) | Tri-Color LED: Configures the behavior of tri-color LED lines (Off/Green, Off/Red, Red/Green; default = Off/Green). Note: The Tri-Color LED control is only available on the Pass/Fail LED output line.
   Acquisition Start Acquisition End Acquisition Missed Job Load OK Job Load Fail | Pulse Length (ms): Duration of an output pulse (1 - 1000, default = 10).
   Job Completed | Pulse Length (ms): Duration of an output pulse (1 - 1000, default = 10). Time After Trigger (ms): When this checkbox is selected, the output will be fired no earlier than the specified amount of time (0 - 10000, default = 0) after the actual acquisition starts. If the time specified for the Time After Trigger has already expired by the time the job completes, the output is fired immediately. If the time specified for the Time After Trigger has not expired by the time the job completes, the output is fired after the specified amount of time.
   Strobe/Light Control Trigger | Strobe/Light Control Trigger: The rising or falling edge of the signal can be used to trigger a strobe. NPN Configuration: If set to Rising Edge, the signal is HIGH when the image sensor is being exposed, otherwise the signal is LOW. If set to Falling Edge, the signal is LOW when the image sensor is being exposed, otherwise the signal is HIGH. Always pulsed for the duration of the exposure. The Exposure time must be 0.50 ms greater than the strobe pulse duration specified on the external strobe device. PNP Configuration: If set to Rising Edge, the signal is LOW when the image sensor is being exposed, otherwise the signal is HIGH. If set to Falling Edge, the signal is HIGH when the image sensor is being exposed, otherwise the signal is LOW. Always pulsed for the duration of the exposure. Always pulsed for the duration of the exposure. The Exposure time must be 0.50 ms greater than the strobe pulse duration specified on the external strobe device. Strobe Start Position: Specifies when the strobe should pulse. Acquisition Start: Specifies that the strobe will pulse as the vision system begins its acquisition. Trigger: Specifies that the strobe will pulse upon receiving a camera trigger event.
